Hrmm I just got done watching the Atkins rotary rebuild video and the guy didn't use a front cover gasket or oil pan gasket, can I do this too.....I assume it would be better but not sure about the front cover omp oil o-ring

 

For Zenki cars, DON'T use a gasket.
Kouki cars require the gasket.
Mazdatrix has the write-up on why...

make sure get the good rtv silicon, one that is more fuel resistant.

 

Specific sealants (ie high temp etc) are equivalent to gaskets, atleast In my experience. The only time I wouldn't use a sealant alone Is on the LIM.
